OV uses a u4/u8 zero-point tensor for dequantization, while GGUF models store FP biases. The current code first extracts an FP bias ov::Tensor from the model and then creates a separate zero-point tensor during model conversion. This PR changes the flow so that the zero-point tensor is created directly during model loading.
